VENTILATOR.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed August 6, 1918. Serial No. 248,515.

To all whom it may concern Be it known that I, GEORGE C. Bnnmnn'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

My invention relates to a ventilator, and has for its primaryobject to provide a novel and inexpensive ventilator which will have a maximum capacity for withdrawing impure air from the'interior of a building or other structure to which. it may be applied without permitting rain or other foreign matter to enter such building through the ventilating passage.

The invention, more specifically, contemplates a ventilator consisting of a hollow structure having a novel arrangement of openings in its side whereby drafts of air will enter one or more of the said openings, irrespective of the direction in which the wind may be blowing, and pass through the ventilator from one side thereof to the other. a I

A further object is to provide novel arrangements and constructions of corrugated deflecting panels adjacent the openings in the sides of the ventilator, which direct the drafts of air entering the ventilator across the ventilating passages in a manner to ac celerate the discharge of impure air, and which are effective in preventing eddy currents of, air or. back drafts from entering the building through. the ventilating passage.

The invention has for further objects such other new and improved arrangements and construction of parts,hereinafter described and claimed, for carrying out the above stated objects and such other incidental objects as will appear from the vfollowirng description. v a

The invention is illustrated, in a preferred embodiment, in the accompanyingidrawings wherein Y Figure 1 isa side view in elevationof a ventilator, constructed in accordance with my invention, applied to theroof of a building. i Fig. 2 is a sectional plan, on an enlarged scale, taken on line 2-2 of Fig.1;

Fig. 3 is a vertical section through the ventilator, taken on line 3-3 of Fig. 2. F fiis a fragmentary-view in section,

illustrating the connection between the top and side sheets of the ventilator, the same being made on a larger scale than that shown in Fig. 2.

Fig. 5 is a View similar to Fig. 4. illustrating the connection between the side and bottom sheets of the ventilator.

Fig. 6 is a fragmentary plan section showing the manner in whlch wire netting is secured across the openings in the sides of the ventilator, and 5 Fig. 7 is a fragmentary vertical section taken through the top sheet and one of the deflecting panels.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, the ventilator is designated generally at 10 and is shown applied to a ventilating stack 11 of the usual form which is secured to the ridge of a gable roof 12. The ventilator consists of a box-like structure or hood made up of a top sheet 13, side sheets 1a, and bottom sheet 15. The edges of the top sheet are bent to form U-shaped beads 16 which interlock with books 17 formed by bending over the upper edges of the side sheets 14. Thisform of connection makes a water tight joint between the top and side sheets and prevents any water, drained off the top sheet 13,-from entering the interior of the ventilator. -The lower edge of the side sheet i l and the bottom sheet 15 areformed with similar interlocking beads 18 and 19 which prevent water running off the side sheets from entering the interior of the ventilator. The side sheets are spaced apart so as to provide openings 20 at the vertical corners of the hood 10 to permit drafts of air to pass through the interior ofthe hood irrespective of the direction in which the wind may be blowing. These openings are preferably coveredwith strips of wirenetting 21 secured in beads 22, 22 formed on the adjacent vertical edges of the side sheets 14. The wire netting is preferably of a large mesh and stands within the vertical edges of the side sheets 14 so as not to interfere with air passing through or across the spaces 20 intervening between the edges central orifice 23 which is preferably annularin shape, the edge thereof being turned .105 of these sheets.v The bottom sheet .14: has a fice 23 is preferably formed into a cone 25 and secured to the center of the top sheet 13 so as to prevent the accumulation of water onthe top of the venti ator. A tubular neck 26, providin a ventilating passage 27, extends through the orifice 23 of the bottom sheet and provide an upstand ingfiange 28 surrounding said orifice The flange 2e rests upon an enlargement 29 of the neck and is slightly larger in diameter than the neck so as to permit any rain, blown into the ventilator through the openings 20, to pass out at the joint between the fiangeil l' and the outer surface of the neck. The hood may be riveted or otherwise secured to the neck so as to make the structure rigid, though this connection should not provide a water tight joint. it will be obvious that the upper endof the ventilating stack 11 could be used as the neck portion of the ventilator if desired.

Drafts of air entering the ventilator through the openings 20 are directed through the ventilator toward another opening 20 by means of air deflecting panels 30 which are arranged opposite the openings 20. These panels are substantially V-shaped in cross-section and are spaced apart to provide discharge openings 31 whichc'ommunicats with the ventilating passage 27 in the neck. These panels are also preferably formed with transverse corrugations 32 which provide horizontal channels which dlrect'the air impinging agalnst the panels in a horizontal course across the discharge openings 31 and prevent swirling or eddy currents within the ventilator.

Referring to Fig. 20f the drawings, it will be noted that drafts of air blowing in the direction indicated by the unfeathered arrows willenter the openings designated A-B and pass across the discharge open ings designated C-D and exhaust through openings Draft of air blowing in the direction indicated by the feathered arrows will enter the ventilatorthrou'ghthe opening A, pass across the discharge'opening' D-G, and exhaust through the openings El3.' The drafts of air passing across the discharge openings 31 in this manner create a suction which causes the air from the interior of the building to be drawn out through the passage 27.

lVhile I have shown and described '1ny invention in one specific embodiment, it will be obvious that modlfications can he made without departure from the spirit of my 1n ent1on. I, therefore, do not wish to limit my invention to the exact structure disclosed except so far as specific limitations may appear in the appended claims- I claim; V V l.
